“Brazil, I’m devastated that I’m not well enough to come to Rock In Rio,” she wrote.

“I would do anything 4 u but I have to take care of my body right now. I ask for your grace and understanding, and promise that I will come back and perform for you soon. I’m so sorry, and I love you so much.”

The singer also posted another snap of a close-up of her Rio tattoo on the back of her neck.

She told fans: “I was taken to the hospital, it is not simply hip pain or wear and tear from the road, I am in severe pain. But am in good hands w/ the very best doctors. Please don’t forget my love for you.

“Remember years ago when I tattooed Rio on my neck, the tattoo was written by children in the favelas. Rio. You hold a special place in my heart I love you.”
